In 2024, real-life "Twisters" chasers use Doppler-on-wheels (DOW) and drones to penetrate the rear-flank downdraft.
In reality, a "twister" is a violently rotating column of air extending from a thunderstorm to the ground.

The entertainment industry capitalized on this volatility, but it also educated the public on safety.
